a/c will not come on?

Check fuse,s and ac relay.

We did all is well there any other suggestions?

Check freon?

Have you ever "overfilled" your gas tank? If fuel backs up in the filler pipe and flows over the edge, there is a sensor that is tripped. On my 2002 Focus, this also had the effect of messing up the A/C operation. I only get A/C with the selector turned to "defroster" and the fan on 2, 3, or 4. Try that, and see what you get. If you do get A/C this way, you can have the sensor replaced at the dealer to the tune of 600-700, as they have to empty and drop the fuel tank to get to where the sensor is. Best of luck!
